Final answer:
The correct answer is c) Horse, which is identified as a pseudo-ruminant due to its three-chambered stomach and large cecum that ferment and digest cellulose from plant material.
Step-by-step explanation:
Ruminants and pseudo-ruminants both have specialized digestive systems to handle their diet rich in plant material. The difference between them lies in the number of stomach chambers they have and where the fermentation of roughage takes place. A pseudo-ruminant is an animal that digests plant material with the help of microorganisms in a three-chamber stomach system and a large cecum, where fermentation occurs.
The correct answer to the question of which animal is a pseudo-ruminant is c) Horse. Horses have a large cecum that is responsible for fermentation and digestion of cellulose from plant material. This distinguishes them from true ruminants like cows, deer, and goats, which have a four-chambered stomach including the rumen, reticulum, omasum, and abomasum for the digestion of roughage.
